Before working on your sales tax return, collect all sales information for the tax period. The MyTaxDC system will guide you, but you will generally need the following information.

Key reporting figures
In addition to your gross DC sales, filing a return requires:
- Total sales and income
- Total taxable sales by category (note: DC has different rates for different categories — general merchandise at 6%, alcohol/restaurants at 10%, parking at 18%, accommodations at approximately 15.95%)
- Non-taxable sales and exemptions
